Thanks Moritz,
I thinked in first time r.lake. About this, it's possible setting the volume of
water with r.lake?
No, that's why I proposed to take the problem backwards: create a lake,
then calculate its volume. You will then have to iterate in order to get
closer to your desired volume, i.e. if the calculated volume is to high,
reduce the water height of the lake, if the volume is too low, increase
the water height.
There are maybe better options, but that's what I can see as a possible
path...

My goal it's view the level that water reaches inside
the raster. What tools can I use in GRASS GIS?
I'm not sure I undertand
your question 100%. What do you mean by "how
water accumulates in lower parts" ?
Possibly some combination of
r.lake + r.volume would allow you to go
backwards and see which volume of water you
have at different lake levels.
